Hi ,
Im experiencing publishing problems with my app. App working fine in my computer but when try to publish it the app crash. Here is the code im using and the log file from shinyapps.io
i also fall in this problem..i can't publish my app.
You shouldent be using an absolute path for the css file because when deployed to the shinyapps.io servers the app doesn't have access to you local files anymore, you have to always use relative paths.
